Mould requirements when an HR system is used

Use of HR systems is most commonly linked to long-series production. Modern moulds 

When ordering HR moulds, the toolmaker employed should always be one who has the appropriate equipment and experience for the job, both in providing the HR system specified, and in manufacturing moulds of the given type, e.g., moulds for medical products, packaging, precision parts, optical components, large containers, and so forth. References should always be checked and suitable warranties obtained. 

The reliability and durability that are a feature of modern moulds are reflected in their price, which sometimes exceeds the price of the machine. It is already normal to expect moulds for large-scale production to last over 10 million cycles.

Considerable rigidity is required of the whole item, especially in the HR distributor area,
